Silicon Nitride is one of the hardest ceramics that has both exceedingly high strength and toughness and exceptionally high thermal shock resistance -- making it ideal for applications with high dynamic stresses, thermal rigor, and demanding reliability requirements. Si3N4 is mainly used in severe environments which combine extreme temperatures with abrasive and corrosive medium.
Possessing of many excellent performances as high strength, high hardness, high fracture toughness, high temperature resistance, wear resistance, corrosion resistance, small thermal expansion coefficient, good thermal shock resistance, etc., Silicon Nitride ceramics could be increasingly used in modern science and technology and industrial fields, such as metallurgy, machinery, energy, automotive, semiconductor and chemical industry.
The main applications are as follows:
✔ Tube and ring faces for mechanical seals
✔ Pump and valve components
✔ Heating tubes for thermocouple
✔ Tools for semiconductor processing equipment
✔ Welding pins and nozzles
✔ Cutting tool
✔ Engine parts in high temperature
✔ Ceramic bearings
✔ Metallurgical products in high temperature
✔ Chemical corrosion-resistant and wear-resistant parts
✔ Aerospace industry
✔ Semiconductor industry
✔ Other applications
